Using a TE120P for outgoing calls only?

Asterisk Asterisk Support
1

Hello,

I have a TE120P that I would like to use for outgoing calls. It’s connected to a partial T1 that has 9 voice channels allocated. I don’t yet have any handsets hooked up to it, so I’m just testing with .call files and attempting to dial my cell phone.

The problem is that the call looks like it’s placed correctly, but the call is supposedly answered about 1 second after it dials out. My cell phone never rings though. Looking at my config, does it look like things should be working? Thanks!

Connected to Asterisk 1.2.22 currently running on asterisk01 (pid = 2204)
Verbosity is at least 8

A T1 needs to be setup as a PRI, not FXS.

Your T1 zaptel configs are not correct.

It’s not a PRI though; why would I configure it as one?

4

Uhm, a T1 is always going to have PRI signaling when used for voice calls. Well, not always, but I’ve yet to see one in practice that wasn’t.

Run a zttool and see what it says. You’re probably running a red alarm.

5

Nope. All green. I don’t need any of the bells and whistles provided by PRI signaling since this will be used for outgoing calls only.

For what it’s worth, the TE120P does not support kewlstart according to Digium documentation.

Pages 31-32 of “TE120P-user-manual.pdf” is using “fxo_ks” signaling in the example. Could you please point me to the documentation that you are seeing?

digium.com/en/docs/misc/signaling.php

Signalling modes for their TE hardware.

A bit old, and I’d be much more inclined to believe the direct product documentation.

Interesting…

Are you using a channel bank? Silly question, but your TE120P is connected in to a T1 drop provided by a phone company, correct? Do you have any DIDs yet that you could try dialing in to?
